Description Eugene Teo (Security Response) 2008-07-14 16:23:49 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-2148 to the
following vulnerability:

The utimensat system call (sys_utimensat) in Linux kernel 2.6.22 and other
versions before 2.6.25.3 does not check file permissions when certain UTIME_NOW
and UTIME_OMIT combinations are used, which allows local users to modify file
times of arbitrary files, possibly leading to a denial of service.
